Your body is rebuilding like crazy from all damage every day. It needs amino acids for this process to make new cells and keep the muscle mass intact. If you do not get enough protein, your body still needs those amino acids for repair, and it will breakdown your own lean body mass to get them.... This wasting during treatments can be severe if you cut protein from your diet.

Just because someone wrote a book on something doesn't make it right. A nutritionist at the hospital can confirm this with you. There are tons of old wives tales out there about what to do during cancer treatments or to not get cancer in the first place. The vast majority of these do not stand up to scrutiny and were conjured up by someone trying to sell people something... a supplement, a book, whatever.
